The defense attorney for a 35-year-old man who killed his ex-girlfriend and her teenage daughter has called for an examination of law enforcement policies and procedures when it comes to dealing with domestic threats and disputes.

Senior Public Defender Noel Larrivee says his investigation of the shooting deaths on Christmas Day 2010 found lapses in judgment, missed opportunities and poor communication between law enforcement agencies leading up to the killings just east of Kalispell.

Kalispell Police chief Roger Nasset tells the Missoulian that he reviewed the agency's response and found no shortcomings.

Tyler Michael Miller pleaded guilty to two counts of deliberate homicide in December for killing 35-year-old Jaimi Lynn Hurlbert and her 15-year-old daughter, Alyssa Burkett.

Miller received two consecutive life sentences earlier this month.
